Small fixes

Just a bit more error handling. Errors get masked after a dialog, as I've discovered.

More fixes

more fixes and balance stuff

I just can't get it right, can I. *sigh* At least now it should work, and I also fixed a couple of typos.

(esp now that splitLines is kinda irrelevant since we use font:draw)

Fixed textzones being too spacious/cut off sometimes as a consequence (when they have many tall letters).

Ice Storm stays in place after the source is dead (just in case); map effects actually check for duration set to 0

Backup guardians consistently increase material level on all zones (hello never-dropping Crystal Heart).

Effective stats fix

Hm, turns out exactly one place WAS using the weird form of outformat I replaced. Well, shed no tears for the dead, as the new version now compares effective stats more accurately-ish!

Small fixes

* Cursed Aura save compatibility
* Talent error fix

Inventory fail fix a.k.a. I'm sorry I thought it checked slots, people are wearing hats on their feet.

Turns out I accidentally broke effective stats comparison. Well, now it's back and better than ever.

Colors are a bit off though? For negative difference.
